The two amino acids which has two chiral centers need to be found out and the configuration need to be assigned. Concept introduction: Amino acids are compounds with difuntional group, amine and carboxylic acid group. There are about twenty naturally occurring amino acids. Each amino acid has atleast one chiral carbon in it except glycine. A chiral carbon is the carbon which is bonded to four different groups. To find : To find the amino acids that has two chiral centers

Question

5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn. H3C CH3

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Interpretation Introduction

Interpretation:

The two amino acids which has two chiral centers need to be found out and the configuration need to be assigned.

Concept introduction:

Cahn-Ingold-Prelog convention can be applied to derive the configuration of the chirality center depending upon the priority of the groups attached. The atom which has higher atomic number gets the higher priority followed by the others atoms. After assigning the priority and numbering, if the sequence 1-2-3 is in clockwise rotation the configuration is assigned as “R” and if it is in counterclockwise then it is assigned “S”.

To find : To find the configuration of the two chiral centers in the amino acids possessing two chiral centers
